He was stationed on Reach during its fall and ordered Noble Team to investigate the comm blackout at the Visegrád Relay.[2]Noble One, would soon report to him that the Visegrád Relay was taken out by a Covenant advance team. He would soon order them to defend Sword Base from Covenant attack, and later take out scattered Covenant anti-air turrets to clear the way for the UNSC Grafton.

After the Grafton was destroyed by a Covenant supercarrier, he approved the plan for Noble Six to pilot a YSS-1000 Sabre along with Jorge-052 to assist in Operation: UPPER CUT and destroy the supercarrier. During the space battle he had the UNSC Savannah assist Noble Five and Noble Six by keeping the corvette they were attempting to board busy. After Jorge and Six boarded the corvette he ordered the Savannah away, when it reported it was under heavy fire, however it was too late and the frigate was destroyed.

Later, Holland contacted Noble Team, now in New Alexandria, on an open channel. He ordered them to destroy Sword Base, which was now under Covenant control. It is not known what happened to Holland but he likely escaped Reach when the majority of the UNSC forces retreated from the planet or was killed during the invasion.

Despite being a fairly major character in Halo: Reach, Holland does not have a character model for in-game or cinematic use. His appearances include a small profile image on monitors during Noble Actual and Long Night of Solace, radio transmissions throughout the game, and a few documents within Catherine Halsey's journal.
